What are the aspects that need to be paid attention to in the distribution and installation of optical cables? It is very important for construction personnel to understand this knowledge. The difference between optical fiber cables and cables is very large. This includes the recyclable nature. Since the optical fiber is a fragile glass fiber, the internal space requires a strict price comparison for the precision link. Therefore, ZR Cable cautions that if damage is done, repair is not realistic.
Distribution and installation of optical cables
1. Lifting equipment such as forklifts or special steps should be used when loading and unloading optical cables.
2. It is strictly forbidden to lay or stack the optical cable reels with optical cables, and the optical cable reels in the carriage must be fortified with wooden blocks.
3. The optical cable should not be reversed multiple times to avoid the integrity of the internal structure of the optical cable. Before laying the optical cable, a single reel inspection and acceptance should be carried out to check the specifications, model, quantity, test length and attenuation. Each optical cable is attached to the guard plate. There is a product factory inspection certificate (should be kept in a safe place for future inquiries), and be careful not to damage the optical cable when removing the cable shield.
4. During the construction process, it should be noted that the bending radius of the optical cable shall not be less than the construction regulations, and the optical cable is not allowed to be excessively bent.
5. The overhead optical cable should be pulled by pulleys. The overhead optical cable should avoid friction with buildings, trees and other facilities. Avoid dragging the ground or rubbing with other sharp and hard objects to damage the outer skin of the optical cable. If necessary, protective measures should be installed. It is strictly forbidden to forcibly pull the optical cable after jumping out of the pulley to prevent the optical cable from being crushed and damaged.
6. When designing the optical cable line, try to avoid the easy building. If it is unavoidable, the optical cable should take fire protection measures.
7. In the construction of the optical cable with the comparative length, if it needs to be reversed, the optical cable must be placed in accordance with the "8" dial. Leave the cable fully twisted.
8. The selection of optical cable splice boxes must meet the requirements of the YD/T814-1996 standard, and ensure that the curvature radius of the optical fiber in the splice box is not less than 37.5MM, and the remaining length of the optical fiber in the splice box is not less than 1.6M. The reinforcing member is firmly fixed on the splice box, there is no twist between the optical cable and the splice box, and the splice box has excellent sealing performance, which can prevent the entry of water vapor.
9. When the optical cable is connected, the joint attenuation should be based on the average value of the OTDR bidirectional test.
10. The laying of the optical cable is completed. If the connection cannot be processed in time, both ends of the optical cable should be sealed to prevent moisture from invading the optical fiber.
11. When the optical cable is connected, if it cannot be connected for many times, it is recommended to cut off a section before connecting (because the cable end may be mechanically damaged during construction).
12. After the optical cable connection is completed, an appropriate amount of optical cable should be reserved at both ends of the optical cable joint box, and it should be firmly coiled on the remaining cable rack.
13. The optical cable reel equipped with optical cable should be rolled in the direction marked on the side panel of the reel. The distance should not be too long, generally not more than 20 meters. When rolling, care should be taken to prevent obstacles from damaging the packaging board.
ZR Cable reminds the distribution and installation of optical cables what needs to be paid attention to. It can be said that optical communication has become the main method of network transmission now, and every link in network engineering needs to be treated with caution. Only in this way can the quality of our projects be guaranteed for a long time.
